Granted: 2009-07-14
Abstract: The invention relates to a catheter and a method of placing a catheter that includes a substantially tubular body portion having an outside diameter no less than the inside diameter of an opening in a catheter introducer adapted to insert a portion of the catheter into a patient's body. The catheter also includes a transition member portion adjacent to a first end of the tubular body portion. The transition member portion has an outside diameter that is less than the outside diameter of the tubular body portion and less than the inside diameter of the opening in the catheter introducer. The invention contemplates that the transition member can be coupled to the end of the tubular body portion, integrally formed with the body portion, or extends from the end of body portion and be removable from a distal end of the body portion. A benefit of the catheter including a transition member portion having an outside diameter that is less than the inside diameter of the opening in the catheter introducer is that it allows a means for inserting a through the introducer catheter which is larger than the inside diameter of the introducer. This provides the benefit of OTN insertion with regard to needle size, but allows for a larger catheter to be placed in the vein by the subsequent removal of the introducer once the transition member portion is placed in the vein.

Abstract: A paint roller frame includes a handle having a radial bore and a wire shank having an outer end for rotatably supporting a paint roller cover and an inner end rotatably received in the bore. The outer end of the wire shank extends at an angle relative to the inner end whereby turning movement of the inner end within the bore will cause a change in the orientation of the outer end and thus the paint roller cover supported thereby relative to the handle. Between the inner and outer ends of the wire shank is an intermediate portion extending at a right angle relative to the inner end which is spring biased into engagement with any one of a plurality of notches in an end wall of the handle surrounding the bore for retaining the outer end of the wire shank in any one of a plurality of different orientations relative to the handle. A pushing force applied to a button or the innermost end of the wire shank will cause the intermediate portion to move out of engagement with any one of the notches thus permitting the inner end of the wire shank to be turned within the bore to change the orientation of the outer end relative to the handle.

Title: Engine driven inverter welding power supply
Inventor: LI STEPHEN
IPC: B23K9/10
Filed: 1998-05-06
Granted: 2003-12-02
Abstract: A method and apparatus for welding with an engine driven inverter power supply includes generating an ac output with an engine and generator. The output is rectified and inverted to provide an ac inverter output. The engine is controlled using feedback indicative of a welding output operating parameter.  The feedback may also be taken from the inverter or generator, and the generator may be controlled instead of or in addition to the engine. Engine parameters that may be controlled include engine speed, selecting between an idle speed and a run speed, a throttle position, a fuel pump, an injection timer, a fuel to air ratio, fuel consumption and ignition timing. Another aspect of the invention is having the feedback be responsive to one or more of the welding current, welding voltage, welding power, or functions thereof.  The feedback may be responsive to the current, voltage, power, ripple and functions thereof.  An aux power output is derived directly from the generator and feedback from the aux load is used to determine if the engine should be idling or running at high speed.

Abstract: A method of arranging a plurality of directional beams (61-64)in a cellular radio system having a plurality of antennas each communicating over a corresponding respective sector area. Interference between geographically close sectors is reduced by the method resulting in an improvement in carrier to interference ratio performance. Carrier frequencies of inner two beams transmitted by antenna an exchange for inner two beams which are transmitted in substantially the same direction by another antenna. This results in an improvedcarrier to interference performance for all four beams transmitted by the antennas. The techniques disclosed are applicable to center-excited or corner excited (tri-cellular) systems.

Title: Salt formulation and process for production thereof
Inventor: DIOSADY LEVENTE LASZIO
IPC: A23L27/40
Filed: 1998-05-28
Granted: 2007-08-21
Abstract: A novel formulation with improved resistance to the breakdown and loss of iodine from fortified food components, especially salt, has been developed. The salt formulation relies on the encapsulation of the iodine compound in a digestible, inert matrix that forms a physical barrier around the iodine compound, and thus prevents reaction of the iodine compound with other components in food, salt or atmosphere, which would otherwise lead to loss of iodine. An especially preferred embodiment is useful in the double--fortification of salt with iodine and iron.

Abstract: The invention provides an electrical switch for monitoring stroke adjustment of an air brake as used on heavy wheeled vehicles. The switch has a switch body securable to fixed structure of the air brake, and fixed and moveable electrical switch contacts in which the fixed switch contact is fixed relative to the switch body. A switch actuator moves relative to the body and carries the moveable switch contact into and out of engagement with the fixed switch contact. The switch actuator is selectively responsive to movement of brake mechanism associated with the air brake actuation. A resilient member cooperates with the switch actuator and the body to close the switch contacts. The switch actuator passes through an opening in an air chamber of the brake and, when the brake is properly adjusted, is clear of a diaphragm plate within the chamber. As the brake is used, brake stroke adjustment eventually exceeds acceptable limits and the diaphragm plate contacts the switch actuator which is moved to open the contacts to actuate a monitor to warn the vehicle operator. The switch is fitted to an existing brake chamber using fasteners passing through openings in the chamber, or can be fitted adjacent the chamber using a bracket secured to existing fasteners.

Abstract: A method for use in the construction of a color display screen using deposition of a plurality of electroluminescent materials onto a substrate bearing said screen. The method comprises the forming operations a), b), and c) in any sequence: a) forming on the substrate a first screening pattern of deposition sites covered with a first material selectively strippable by a first agent; b) forming on the substrate a second pattern of deposition sites covered with a second material strippable by a second agent; and c) forming on the substrate a matrix surrounding the first and second patterns of deposition sites. The method includes thereafter performing a first stripping of the first material with the first agent to reveal first deposition sites within the matrix and performing a first depositing of a first electroluminescent material within the first revealed deposition sites. Following the first stripping and depositing, the second material is stripped with the second agent to reveal second deposition sites within the matrix and a second electroluminescent material is deposited within the second revealed deposition sites. By the practice of the disclosed method the forming operations are segregated from the electroluminescent material depositing operations.

Abstract: A method and a system in which a computing system transparently accesses resources connected to the Internet. A memory of the computing system contains an operating system, a cache associated with the operating system, a shared library and an access server. The shared library is responsive to a system call for a file by determining whether a path name for the file is located under a personal name space in the memory and by issuing a request for retrieving the file from an Internet resource based on the path name located under the personal name space when the file is not stored in the cache and has a path name located under the personal name space. An access server, in response to the request from the shared library, selects an appropriate access protocol for retrieving the file from the Internet resource and retrieves the file from the Internet resource. The shared library then issues the system call to the operating system when the access server retrieves the file. The access server restores the file to the Internet resource when the application closes the file.
